Muffler for 2006 Lucerne CXS


Asked by jfk34 Sep 07, 2016 at 01:01 PM about the 2006 Buick Lucerne CXS FWD

Question type: Maintenance & Repair

Anyone found a muffler that can replace just the muffler on the all in one
exhaust system?  I can cut it off and replace, just need to find one that fits.  
Any help is appreciated as I do not want to replace the entire system as it is
still like new minus the mufflers.

Any aftermarket parts store should be able to come up with one, just give them the diamensions of the muffler, size of the inlet and outlet pipes and if the pipes are straight through or offset. When I worked for a parts store we were all the time matching mufflers that way.

After 3 auto parts stores and hours of searching the internet I found no standard muffler listing for a 2006 Lucerne CXS with the 4.6 Northstar engine. I decided to look at a 2006 Cadillac DTS because it has the same engine, and found AP brand muffler 700374. It's 1" longer than stock but with the length you loose cutting the old muffler out it worked really good.
